Spatial audio that's
provably correct

The only spatialization engine with deterministic, SHA-256 auditable, bit-reproducible renders. Built in Rust. Zero black boxes.

✓ Identical. No DAW or spatializer on the market can guarantee this.

Four irreplaceable differentiators

Not another convolution reverb. A complete, auditable spatial audio pipeline.

🔐

Deterministic & Auditable

Every render produces a SHA-256 fingerprint, config version, parameters, and timestamp. Prove to any QC house exactly how audio was processed — months later.

👂

User Calibration Profile

Fixed HRTFs sound "in-head" for most people. SAVFS profiles your ITD, ILD, and perceptual EQ so sources externalize correctly in 3D space.

🌐

Full Ambisonic Pipeline

AIAS architecture: every input encodes to a Higher-Order Ambisonics scene first. Decode to headphones today, 7.1.4 tomorrow — same source, zero re-render.

📊

Broadcast-Grade Metering

Integrated LUFS and True Peak measurement (ITU-R BS.1770-4). Every processed file is validated automatically against Netflix and Apple TV+ delivery specs.

🔌

CLAP + VST3 Plugin

Drop directly into Reaper, Nuendo, Bitwig, or any CLAP/VST3 host. Real-time binaural spatialization on any mono or stereo source.

Built in Rust

Zero runtime dependencies. Ships as two standalone executables (CLI + UI). No installers, no DRM dongles, no internet required after activation.

Who needs this

SAVFS pays for itself in one prevented delivery rejection.

Use Case Why SAVFS
Netflix / Apple TV+ deliverySpatial audio compliance required since 2024 — SAVFS validates LUFS + True Peak in one pass
Post-production QCAuditable proof that spatialization met spec, acceptable in contract disputes
Broadcast automationBatch-convert libraries with per-file audit trail; defensible to regulators
Game audioOffline spatialization pipeline for asset libraries; bit-identical per build
Music productionBinaural mix reference competing with Dolby Atmos at a fraction of the cost
VR / XR developmentFast offline rendering of positional audio assets; deterministic build artifacts

Frequently asked questions

What does "deterministic render" actually mean?

Given the same input WAV, the same spatial parameters (azimuth, elevation, distance), and the same SAVFS version, the output is bit-for-bit identical every single time. The SHA-256 hash of the output file will never change. No floating-point non-determinism, no random seeding, no DAW-buffer-size dependency.

Do I need an internet connection to use SAVFS?

No. After license activation (one-time, online), SAVFS runs fully offline. The executables have zero external dependencies — no cloud calls, no phone-home, no telemetry.

Which DAWs does the plugin support?

The CLAP plugin works in Reaper, Bitwig Studio, and any CLAP-compatible host. The VST3 plugin works in Nuendo, Cubase, Studio One, Reaper, and any VST3 host. Both deliver the same deterministic processing.

Is the license perpetual or a subscription?

Personal and Studio licenses are perpetual one-time purchases. You own SAVFS 1.x forever. Minor updates (1.1, 1.2, …) are free. Major version upgrades (2.0+) have separate upgrade pricing. Enterprise is annual, which covers all updates and API access for that year.

Can I transfer my license to another computer?

Yes. Each license can be deactivated on one machine and activated on another. Personal (1 device) and Studio (5 devices) enforce concurrent activations, not lifetime transfers.

What are the system requirements?

Windows 10 or 11 (x64). Any WASAPI-compatible audio interface. Headphones are required for binaural 3D effect. No special GPU or SIMD hardware required — SAVFS is optimized for standard x86-64.

Is there a trial version?

We offer a demo session via video call where we process your own audio files live. Email us to schedule one. This lets you see the audit trail and bit-identity proof on your own material before purchasing.
